A case of Tropical ataxic neuropathy

Abstract Tropical ataxic neuropathy is endemic to certain parts of the world and is causally related to the regular long term intake of cassava. The Cyanogen, Linimarin and its subsequent metabolism leading to the release of cynanide and thiocyanate and the development of deficiency of sulphur containing amino acids lead to the neurotoxicity which presents as predominant sensory neuropathy with ataxia. We report a young patient from Tanzania with the disease and highlight the importance of dietary history in patients with unexplained neurological illness.
